The following is essentially my 'theory of everything'. I just felt like sharing with you, and would love to know what you guys think of it.
In truth, any given 'particular thing' (for example, a tree) can ONLY exist if the right conditions are present. These conditions are 'not the tree', and are necessarily comprised of 'other things', ALL of which can ONLY exist if the right conditions are present. These conditions are 'not those other things', and are necessarily comprised of 'other other things', ALL of which can ONLY exist if the right conditions are present....and so on, ad infinitum.
Therefore, 'the tree' could not possibly appear in exactly the way that it is without the ENTIRETY of 'not the tree' (which is, in this context, most accurately defined as the all-inclusive and as such fundamentally singular and ultimately boundless presence that lies beyond 'the tree') appearing in exactly the way that it is.
In this way, 'the tree' and 'not the tree' are realized to be an absolutely inseparable 'pair' of opposites, which (like ALL such pairs) is inextricably indicative of the 'deeper' (and MORE ACTUAL) Reality that is itself fundamentally seamless and as such completely devoid of BOTH. Therefore, it isn't actually true that there exists EITHER 'the tree' OR 'not the tree', that are intrinsically different from and/or independently other than each other in the way in which they SEEM to be. EXACTLY the same is true of 'Me' and 'Not Me' (and of 'You' and 'Not You').
Upon realizing this, we can rest, and laugh.
. . . you believe that 'something actually exists', that is to say, that Reality is 'something', and therefore, that Reality is finite and temporary.
